IMPROVEMENT IN DUMPlNG-CARS.

Specification forming part of Letters Patent No. 193,281, dated July 17,1877; application filed March 15, 1877.

To all whom it may concern:

Be it known that l, THOMAS PURvmNoE, of Steubenville, in the county of Jeft'erson and State of Ohio, have invented certain new and usefulImprm'ements in Dumping Cars, of which the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which form apart of this specification, and in which Figure 1 is a side elevation ofmy improved invention in a closed position. Fig. 2 is a similar view inan open position.

Similar letters of reference occurring on the several figures indicatelike parts.

My invention relates to that class of dumping-cars in which the car isformed of two sections which discharge their contents at the center; andit consists in pivoting the two sections together at the inner top edgesof the same, and providing a sliding catch or belt at the bottomthereof, all as will be hereinafter more fully described and pointed outin the claim.

Referring to the drawings, A A represent the twosections forming thebody of the car, and which are connected together at the top by thehinge K, upon which the two sections turn to discharge their contentswhen the catch or bolt B at the bottom is drawn back.

The catch or bolt B is adjusted to the bottom of the section A insuitable guides, and is adapted to engage with the pin 0 on the oppositesection A their respective axles, and their contents may be easily andreadily discharged by drawing back the catch B, which causes thesections to turn on the hinge K and discharge their contents. It willalso be observed that the two sections are readily closed by bearingdown upon the end of either section, and secured in place by pushing inthe bolt B.

The advantages of my invention will be readily apparent,inasmuch as acomplete and efficient operation is secured without the aid of pulleysand chains or other intricate mechanism.

lam aware of the patent granted to Merrington and Kirkwood under date ofNovember 1, 1870, and numbered 108,810, and I hereby disclaim theconstruction therein shown; but

What I claim as new and useful is A dumping-car consisting of thesections A A, pivoted together at the upper central part, and providedwith a catch or bolt, B, and pin 0 at the bottom thereof, the severalparts being arranged and combined to operate substantially as and forthe purpose specified.
